Palimpsest (or: How To Destroy Sounds) 2004-10-09T01:01:16+00:00 In the thread following the posting of my latest track, the following bit of dialogue took place: //looks up "palimpsest" Hmmm. Never thought of sounds as palimpsests. Are you referring to the atomic recycling of sounds in the granular process? Sort of, but more the layers of remnants. When you see old hand written manuscripts with stacked erasures, there's this sense of activity in all the bits and pieces. Well, Steve gave me a great idea. How does one scrape layers of sound off an audio-file? The idea is that something new comes out, recycling as it were. If I found a way, I promised Steve, I would let him know. I figured that more people would be interested. Maybe not, but one never knows. The solution was right in front of me. The spectral noise reduction found in tools like Audacity, Goldwave and Acoustica (well, most editors, really) do just that: remove layers of sound. And in a messy way, too, when over-applied. I have just finished stage one. My idea was this: I will use one soundfile as noise-source, and another to be horribly mangled. A bit like convolution, as suggested by Steve, only really destructive. (mwa-ha) I downloaded the promo.mov from the gunbuilders site that was posted by Glassback a couple of days ago (thanks), exported the wave-file and loaded this into Audacity. On the next track, I loaded the raw data from the *.mov. I used this as noise-profile. I applied the profile to the soundtrack, and the end-result was the sound of 100 tin birds chattering. Really cool! I did pitch it down by 2 octaves because the sounds were so high-pitched they were barely audible. Example 01 Experiment two was the reverse: used the sound-track as profile and applied this to the *.mov. Weird whistly sounds wwere the result. Example 02 For experiment three I reversed one instance of the soundtrack and used this as profile. I applied this to a normal version of the soundtrack. Nice wobbly spectral shifting. Like a shortwave-radio signal coming from under water. Example 03 Phase two will be adding a new sound to the palimpsest. Not sure if I sould somehow FFT this on top of the new sound or if I should just use the new sound as source in sampling or resynthesis. Before I start that, I want to try an alternative way of erasing sound. I dug out Hog and found that it does frequency-extracting. This, too, could be an approach. Will try this later. //edit: It just occurred to me that it would have been a better idea to post this in the Music Cafe, with sounds. Oh well, late, tired, &c. //edit 2: Links to examples added.
